Research Abstract

A parabiotic model was created by surgically conjoining one transgenic GFP mouse and one wild-type partner. After shared circulation was established, a transverse fracture with periosteal stripping was created in the contralateral diaphysial femur of the wild-type partner. The fracture site was treated with daily exposure of low-intensity pulsed ultrasound (LIPUS). GFP+ cells that gained access to the osteotomy site via the systemic circulation were identified in the bone-forming site. The findings suggested that LIPUS induced homing of circulating osteogenic progenitors to the osteotomy site for possible contribution to new bone formation.
